kernel/generic: Restore kernel files for v6.6
This is an automatically generated commit which aids following Kernel patch
history, as git will see the move and copy as a rename thus defeating the

Subject: net: sfp: enhance quirk for Fibrestore 2.5G copper SFP module
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Enhance the quirk for Fibrestore 2.5G copper SFP module. The original
commit e27aca3760c0 ("net: sfp: add quirk for FS's 2.5G copper SFP")
introducing the quirk says that the PHY is inaccessible, but that is
not true.
The module uses Rollball protocol to talk to the PHY, and needs a 4
second wait before probing it, same as FS 10G module.
The PHY inside the module is Realtek RTL8221B-VB-CG PHY. The realtek
driver recently gained support to set it up via clause 45 accesses.
